A bad news for Al Gore - A giant slab off in Antarctica's Wilkins Ice Shelf

click on it to view larger image

In the past 50 years the western Antarctic peninsula has warmed by 0.5 degrees Celsius each decade, fastest temperature rise world-wide. This is direct impact of global warming. A team of scientist at University of Colorado’s National Snow and Ice Data Center proved using satellite images that Antarctica’s massive Wilkins Ice Shelf has begun disintegrating. I think this is one of critical indicators of the biggest environmental crisis of the world.

“Wilkins is the largest ice shelf on West Antarctica yet to be threatened. This shelf is hanging by a thread,” said David Vaughan of the British Antarctic Survey. Now a large part of the 12,950-square-kilometre shelf is supported by a narrow 5.6-km strip of ice between two islands

The shelf was triggered February 28 when an iceberg measuring 41 by 2.4km broke off its southwestern front. The effect is nicely shown above picture.

Sustainable approach from Sri Lankan industry

The Gasifire Plant which generates thermal energy equivalent to 1000KWA which is powered by sustainable grown biomass [Gliricidia]

Samson International Ltd is a sri lankan based industry and it has switched from burning 1200 liters of fuel oil a day to 4.45 tonnes of Gliricidia waste per day for their energy generation. This conversion of fossil fuel to sustainable grown biomass [Gliricidia] which cost them LKR 12 millions gave them following advantages.

Increases their contribution towards environment [reducing 842 tons of Carbon Dioxide and 8.2 tonnes]

India's growing gender imbalance

India is one of south Asian country which had gender issues. With development of technology and education many people hope a better community through those advancements. But developing medical technology makes India's Gender inequality more.

In ancient India girls were face troubles after their birth. But now with advancement on medical technologies they are endangered even as a female foetuses. Because a simple Scan will tell the parent about sex of their foetuses. Indian people do not like girls to be as there children because of financial burden, largely because of the dowries that have to be paid.

Source: Al Jazeera



"India is facing a growing gender imbalance -blamed on the widespread abortion of female foetuses. In some states, fewer than eight hundred girls are born for every thousand boys. Girls are seen as a financial burden, largely because of the dowries that have to be paid when they get married. Now the Indian government will start paying parents to help them bring up female babies." - Al Jazeera's Matt McClure reports

But the internet firewall is now being loosen slightly. Now China people have partial access to BBC news website. Now China people access some parts on BBC. The firewall remains in place for Chinese language services on the website and for any links in Chinese.

"Food prices rising across the world" - CNN - Why this happen?

Today CNN (web) report that there is a food price rising all over the world. Yes. In Sri Lanka we are also suffering from that. Many people think that is because of war [war in north east of Sri Lanka to save people from LTTE]. But it is not the only cause.

Petroleum prices, which increase the cost of everything from fertilizers to transport to food processing - [Solution: Do not addicted to fossil fuel, go for alternative fuels. ]

Because of Biofuels extraction from food items such as cassava, wheat starch, rice starch. [solution Try to use non-food bio resources as renewable energy sources. when you develop biobased fuels. Ex. Biogas, Solar, .... etc ]

Due bad weather and poor harvests have a bigger impact on prices. [Solution: Minimize environmental pollution and try to avoid climate crisis.]

Above reasons are global. According to my point of view in Sri Lanka we have another reasons for food price hike. In sri lankan normal economic pattern we do have many intermediate vendors in between customer and farmer. Post harvest damages on food is huge [approximately 20%] and most of food items specifically vegetables and fruits are damaged in transportation. Most of sri lankan used to buy every thing from market while they have enough space and time to maintain a home farm garden to cultivate essential vegetables and food items. I think this is one and main method to fight with increasing food prices. Another improtant thing is we must ensure food security in country and we must promote local production of essential food items. We must change the centralized food item distribution culture [Dambulla and Collombo market] and we must develop a distributed network to transfer food items in between farmers and customers.

We must take this problem serious. Every one should think to do there best. I think with this will cause more hunger deaths world wide. [Read about huger deaths]

Do you have doubts on biofuels future!

We have addicted to fossil fuel and some engineers do not think bio fuel as an option to present fuel crisis. In our department Katha Baha programme (discussions) we usually discuss on alternative fuel such as biogas. At that kind of discussion some of students ask about financial feasibility. But I found very interesting web site on biooil which belongs to Dynamotive Energy Systems. Have a good read on it and identify the present day stability and future opportunities of biofuels.

Some important points in CP implementation on Energy application. Can You suggest more?

• Installing sensors to turn off or power down lights and machineries when they are not in use
• Proper insulation on heating and cooling systems and pipe networks.
• Using more energy-efficient equipment
• Continuous maintenance aiming optimize energy usage in equipments
• Ensuring optimal combustion in hot water boilers and steam boilers
• Eliminate steam and condensate leakages and discharges. (Do not waste condensate, it contain more heat comparatively to make up water of the boiler)
• Using low-grade energy for use elsewhere in operation, such as using furnace emissions to heat up make up water stream.

Are there more options? Can you suggest with your experiences?
